SURPAC, Kriging, Geological modelling, Reserve estimation, Block modelAbstract
As the mines are growing bigger the need for the advancement has also increased. The computer aided mine planning and
design techniques have come as an advantage for mining industry. This project aims to exhibit the implementation of
computer aided mine planning and design techniques in mining industry which gives more accuracy and reliability of mine
plan. Opencast mine planning is a multi-parameter optimization problem which requires simultaneous solution. This project
emphasis on the optimized planning of limestone mine where the ore is categorized into lithologies on the basis of
percentage of CaO present. It uses software such as SURPAC for geological modelling, block modelling, ore reserve
estimation using geostatistical model and pit design. The estimation is done using Kriging which shows that the percentage
of CaO varies from 30.24% to 47.05% which helps in determining the minable ore. It also aims at the optimization of various
techno-economic parameters which play vital role in mine planning and design aspects.
